(Upper limit of ﬂow rate: 10 liters/min. max. for NHM1 & M3 and 3 liters/min. max. for NH-SH1) However, depending on releasing angles, the posture of thehose may be changed by a jetting pressure even when the air/liquid pressure is below the upper limit.

※The magnet section of NH-SH1 is common with NH-M1 and NH-P1 and therefore, the upper section is interchangeable for mounting.
However, for installation of NH-SH1 ﬂexible hose on NH-P1 and M1, a screw conversion joint needs to be procured separately.

※The NH-SH1 ﬂexible part cannot be used in applications where it is bent more than 90 degrees or ﬂexed repeatedly in the same
point as such operations will damage the copper pipe.

Flex●Compared with conventional products, flexibility has been extremely
improved. The ﬂexible part can be bent freely. (NH-M1, M3)●By employing a metallic ﬂexible part, the holding posture is maintained
stably even when releasing high pressure air or a large amount of cutting
ﬂuid. In addition, it is highly resistant to thermal damage by chips and its
durability has been improved. (NH-M1, M3)●The powerful magnet enables the holder to be mounted in any position easily.
●The nozzle tip cab be positioned in any posture and at any angle.
●The holder is equipped with a valve to enable adjustment of the ﬂow rate.
●The adjustable hose can be adjusted in length by removing or adding
joints. (NH-P)●The employment of a copper pipe ﬂexible part has increased the holding
power twice as large as the conventional model (NH-M1). The posture of
the ﬂexible part can be maintained even when releasing high pressure
air. (NH-SH1)●The ﬂow rate can be adjusted at the nozzle tip. (NH-SH1)●The ﬂexible part can be mounted on a conventional magnet by using ascrew conversion joint. (NH-SH1)

These supporters can hold materials having weak magnetic properties
such as carbide and materials such as aluminum, brass and stainlesssteel which cannot be held by magnetic chucks. They are held by a strong
spring force on both sides and secured to the magnetic chuck.
［Features］●These supporters are thin and therefore can be used for relatively thinworkpieces.

This adapter itself is not magnetic, but when it is placed on a V-holder
having the N pole and S pole on separate sides like Model KVA, it induces
magnetism to hold small diameter workpieces that cannot be physicallymounted directly. (See the ﬁgure below.) This adapter is recommended forholding workpieces during grinding, drilling and measurement.
［Features］●The attractive face can be set to any angle between 90 and 180
degrees.

［Application］
The Magpad is a device to prevent wire breakage by heat
due to aerial discharge. It protects wire electrodes of wire
electric discharge machines from scattering of coolant
which is likely to occur at the start of discharging. This
Magpad can also be used to prevent dislocation or fallingof cut-out pieces at the start or end of cutting.
［Features］●The Magpad is made of transparent acrylic plate
incorporating powerful magnets. The Magpad has strong
holding power and enables it to set a wire while
monitoring its position visually.
●No mechanical clamp is required. Attaching anddetaching can be done eﬃciently and without a fear ofdamaging workpieces.
●Various models are available to suit any workpiece
shapes.
●There is no fear of rusting and the magnetic force issemi-permanent. The Magpad withstands repeated use
and therefore is very economical.

YS / MV/ MP / KRS［Application］
Suitable for supporting the overhanging portion of workpieces during machining
and measurement.
［Features］●The support bolt moves up and down as the movable bolt is turned. This design
enables expansion/contraction or up/down movement quickly by one hand.
●Since the support bolt does not rotate, it does not damage workpieces when it
contacts them.
●The movable/support bolts can be locked simultaneously by tightening the knob
to enhance the work eﬃciency.
※ If the knob is likely to be loosened by vibrations, use the included grub screw.
●The use of top and bottom two types of attachments (optional) expands theapplications.
